Abstract

This document specifies a method for the determination of the chloride content in organic fertilizers, organo-mineral fertilizers, inorganic fertilizers and liming materials by potentiometric titration. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: - fertilizers; - liming materials; and where the following category: - organic fertilizers; - organo-mineral fertilizers; - inorganic fertilizers; - liming materials; is the highest % in the blend by mass or volume, or in the case of liquid form, by dry mass. If organic fertilizers, organo-mineral fertilizers, inorganic fertilizers, or liming materials is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. NOTE Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.
